HEATING- SYSTEM FOR RETORT COKE OVENS.

Application filed September 17, 1921. Serial No. 501,263.

T 0 all whomz't mayconcern.'

Be it known that I, JULiUs BECKER, a citizen of the United States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a new and Improved Heating System for Retort Coke Ovens, of which the following is a specification. Y

My invention relates particularly to that type of oven in which horizontally disposed heating flues are arranged in two sets on each side of the oven with a division wall between the two Sets, and the object of my improvement is to provide a system of flues for the delivery of hot air from a regenerator to the heating ues and the discharge of gases of combustion from the heating lues to the regenerator, which shall insure free and uniform movement of the gases and consequent efficient and uniform coking of the oven charge.

The invention will be best understood by reference to the accompanying drawings, forming a part hereof, Fig. 1 of which shows a vertical cross section through a battery of coke ovens partly broken away to show the heating flues; Fig. 2 shows a vertical cross section throu h the heating ilues, and Fig. 3 is a plan view on the line 3-3 30 of Fig. 1.

Referring to the drawings, A indicates the retort, or coking chamber, on each side of which are located two sets, B, B', of horizontally disposed heating ilues, separated by a division wall C, which are supplied with gaseous fuel by burners b, b'.

Below and parallel with each retort are located two regenerators D, D', constructed of checker work brick in the usual manner, and between the regenerators are two air and gas iues E, E', which run lengthwise of the oven block and are arranged to be connected at the end .of the oven block with any usual or convenient form of reversing valve (not shown in the drawings) so that they can be connected alternately with the open air and with the chimney stack, as may be required.

The flue E is connected with the regenerator D by an opening, d, and the flue `E is connected with the regenerator-D by an opening d. From the regenerator D, a flue F, located b'elow the heating ilues, leads to a vertically disposed flue G which passes upward through the division wall iC' be tween the two sets of ilues B, B', to a point above the uppermost flue, 1, where it is di vided into two branches, H, H', which extend along above the heating iiues and are respectively connected, the one, as'H, with the uppermost oven iiue 1, of the set B, and the other, as H', with the uppermost flue 1, of the set B.

The lowermost iues 6, 6, of the two sets of heating Hues are connected by short passages, f, f, and openings g, g, with a sole flue. I, which extends along underneath the retort, A, and from the sole flue I, a passage K leads to the regenerator D'.

In the operation of the oven the air for the support of combustion of the fuel in the heating iiues enters through that one of the flues E, E', which is at the time connected with the atmosphere, as E, and passes thence into regenerator D, and from the regenerator by flue F, riser G, and branch iiues H, H', to the uppermost 'lues l, l, of the two sets of heating iiues. At thel same t time the gaseous products of combustion pass from the oven flues 6, 6, into the sole flue I, and thence by passage K, to the regenerator D',vheating it. From the regenerator, D', the gases pass into the flue .E' and thence to the stack. 0n' changing the reversing valve,`air enters by ue E', into the regenerator D', and thence by passage K, sole lue I, and passages f, f, to the lower# most flues 6, 6, of the' two sets of oven iiues. At this time the gases of combustion pass out of the uppermost oven ilues, 1, 1, by passages H, H' and thence by passages G and F to regenerator D, and so to flue E, and the chimney stack.

The flue system is duplicated on the two sides of the oven, the heating ues on both sides receiving hot air from and discharging hot gaseous products of combustion into the same regenerator.

My invention affords a simple, eicient and inexpensive form of construction in 10o which a minimum of push is required to remove the heavy gaseous products of combustion from the heating fines and by which a v constant and uniform temperature is main- 1. In a heating system vfor retort coke ovens the combination of a coking chamber, two sets of horizontally disposed heating lues on each side of said chamber, and two regenerators located below the chamber and parallel thereto, one of said regenerators being connected with the lowermost heating fines on each side of the chamber and the other being connected with the uppermost heating flues on each side of the chamber.

'2. In a heating system for retort coke ovens the combination with a Coking chamber, of two sets of horizontally disposed heating fines, separated by a vertical dividing Wall, on each side of said chamber, two

regenerators located below and parallel with the coking chamber, a sole flue located below .the chamber, passages connected with one of said regenerators and passing vertically upward through said dividing Walls, passages connecting said vertical passageswith the uppermost flues of said sets of ues, passages connecting the lowermost flue of each ofsaid sets of lues with the sole flue and a passage connecting the sole flue with the other of said regenerators.

In testimony whereof I affix my signature, this 15th day of September, 1921.
